Monk weapon doesnt disappear in preview window

Steps:
1. I put on the Lvl.70 monk set from the class quest, including the weapon Antiquated Sudarshana Chakra
2. Save that as current outfit
3. Try on different items, even with another class active
4. The preview window shows the Sudarshana Chakra in addition to the previewed item, no matter for which slot, the only exception being weapons, those work just fine in the preview
5. This bug remains for at least 3 days so far, so restarting the game has not changed anything so far.

Example pictures (note especially the preview window and at its side the item it is supposed to show):
